  • For F, it is shifted towards left by one position, i.e.. E
  • For B, it is shifted towards left by one position, i.e.. A

Complete the series. 4, -5,11, -14,22, —

Explanation

  • Here, difference between two consecutive terms is an odd number and there is change in sign of that number also.
  • Difference between first pair of two numbers = 1 with change in sign
  • Difference between second pair of two numbers = 3 with change in sign
  • Same way, difference between third pair of numbers should be 5 with change in sign.
  • So, the number becomes, 22 + 5 = 27. With change in sign it will become -27.
